Does anybody know if changing the logic board with an upgraded one is possible in the future on a G5 iMac, if so where would you get the hardware.

I wish. I have been waiting for someone to make a motherboard replacement for my powermac 8500 for years now, so far no joy.

My guess?

1) Probably not
and
2) If ever possible, available only as an Apple Service part at an astronomical price.

The iMac G5 is a highly customized motherboard, and space is very tight. Any modifications that Apple does for "iMac G5 Mark II" could make the new mobo physically incompatible with the existing unit.

Well, you should get a good idea if you look at the market for upgraded logic boards in the iMac G4.

And then realize that the upgraded boards for the iMac G5 are going to be several times less likely to happen -- since you cannot simply desolder and replace the PPC970 and move a few jumpers like you could on the G4s.

The PPC970 is a significantly more complex processor that doesn't follow the "old rules"
